Description

Technical Field

[0001] This utility model relates to the field of traditional Chinese medicine decoction pieces technology, and in particular to an automatic screening and collection device for traditional Chinese medicine decoction pieces. Background Technology

[0002] Prepared medicinal herbs are Chinese medicinal materials that have been processed according to traditional Chinese medicine theories and methods, and can be directly used in clinical practice. During the production of prepared medicinal herbs, due to their natural origin and diverse varieties, the same medicinal material, after slicing, will exhibit different sizes and irregular shapes, such as rotten slices, hollow slices, fragments, and cracked slices, and will also contain a large amount of dust, medicinal debris, and other impurities. To ensure the quality and clinical efficacy of prepared medicinal herbs, it is necessary to perform processes such as impurity removal, grading and selection, and removal of medicinal debris.

[0003] A search revealed Chinese Patent Publication No. CN222556025U, which discloses an automatic collection device for Chinese herbal medicine slices. The device includes a body with two rotating rollers rotatably connected to its bottom surface. A moving track is drivenly connected to the outer surfaces of the two rotating rollers. Two support plates are fixedly connected to the left side of the body, and a conveyor belt is installed between the two supports. A fixing plate is fixedly connected to the left side of the two support plates. This automatic collection device for Chinese herbal medicine slices reduces the crushing of residual spilled materials by installing the moving track, improving the collection effect. The combination of the sweeping plate and the conveyor belt transports the Chinese herbal medicine slices, increasing collection efficiency and achieving automatic material transfer and collection, reducing manual intervention. The combination of the sieve plate and the dust collection frame removes impurities from the Chinese herbal medicine slices and can screen them to remove dregs and stones.

[0004] The aforementioned patent specification mentions the beneficial effects of "automatic transfer and collection reducing manual intervention." While the aforementioned patent offers fast collection, its low screen replacement efficiency affects production efficiency. Therefore, an automatic screening and collection device for traditional Chinese medicine decoction pieces is proposed. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an automatic screening and collection device for Chinese herbal medicine slices, which aims to improve the problem of excessive screen replacement time in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An automatic screening and collection device for Chinese herbal medicine slices includes a discharge mechanism, a screening mechanism slidably connected inside the discharge mechanism, a feeding mechanism fixedly connected outside the discharge mechanism, a driving mechanism fixedly connected to the bottom of the discharge mechanism, and a buffer mechanism fixedly connected outside the discharge mechanism.

[0008] The screening mechanism includes screens, two screens are slidably connected to the inner wall of the discharge mechanism, two limiting holes are opened on the outside of the screens, two sliding columns are slidably connected to the inner wall of the screens, and an adjustment component is slidably connected to one end of the sliding column;

[0009] Through the above scheme, efficient screening is achieved through the coordinated operation of various mechanisms. The feeding mechanism quantitatively delivers the Chinese herbal medicine slices to the discharging mechanism. After the drive mechanism is started, the eccentric wheel drives the screen box to vibrate, allowing the Chinese herbal medicine slices to move fully on the screen. Slices of different specifications are accurately separated through the screen. The screen in the screening mechanism works in conjunction with the sliding column and adjustment components to ensure that the screen works stably when vibrating and can be quickly disassembled and cleaned by a sliding switch when blocked. The buffer mechanism absorbs the vibration impact force through spring 2, reducing the shaking of the discharging mechanism and ensuring the stable operation of the device. The entire system is interconnected, significantly improving the efficiency and quality of screening Chinese herbal medicine slices.

[0010] As a further description of the above technical solution:

[0011] The feeding mechanism includes a stainless steel frame. The inner side of the stainless steel frame is fixedly connected to the outside of the discharge mechanism. A motor is fixedly connected to the outside of the stainless steel frame. A follower plate is fixedly connected to the drive end of the motor. A driven plate is rotatably connected to the other end of the follower plate. A slide plate is rotatably connected to the other end of the driven plate.

[0012] Through the above scheme: the feeding mechanism constructs a stable and precise feeding system. The stainless steel frame serves as the main support structure and is firmly connected to the discharging mechanism, providing a solid foundation for the entire feeding process. Once the motor starts, it transmits power to the follower plate, causing it to make circular motion. Then, through the rotation of the follower plate, the motion is converted into the linear reciprocating sliding of the slide plate. The slide plate slides precisely at the bottom of the stainless steel storage tank. Each time it slides, the opening size and sliding frequency are precisely controlled to achieve a quantitative drop of Chinese herbal medicine pieces. This design ensures that the amount of Chinese herbal medicine pieces entering the discharging mechanism is stable and controllable, avoiding the impact of uneven feeding on the screening effect, and ensuring the continuity and efficiency of the entire screening and collection device.

[0013] As a further description of the above technical solution:

[0014] The driving mechanism includes a support plate, the top of which is fixedly connected to the bottom of the discharge mechanism. A second motor is fixedly connected to the top of the support plate. An eccentric wheel is fixedly connected to the driving end of the second motor. A slide rail is fixedly connected to the outside of the eccentric wheel. A connecting base is slidably connected to the outside of the slide rail. A counterweight is rotatably connected to the outside of the connecting base.

[0015] The above solution provides stable power for the screening process, while the support plate firmly supports the discharge mechanism, ensuring smooth operation of the device. The second motor drives the eccentric wheel to rotate at high speed, generating centrifugal force to create vibration. The slide rail and connecting base work together to transmit the vibration to the discharge mechanism in an orderly manner. The counterweight can adjust the vibration frequency and amplitude, flexibly adapting to screening needs for different textures of Chinese herbal medicine pieces, ensuring that the Chinese herbal medicine pieces move fully in the screening box, and improving screening efficiency and accuracy.

[0016] As a further description of the above technical solution:

[0017] The buffer mechanism includes connecting blocks, and multiple connecting blocks are externally fixedly connected to the outside of the discharge mechanism. A connecting plate is fixedly connected to the bottom of the connecting blocks, and two springs are fixedly connected to the bottom of the connecting plate. A support base is fixedly connected to the bottom of the two springs.

[0018] Through the above solution: the buffer mechanism effectively mitigates the vibration and impact generated by the drive mechanism; the connecting block is tightly fixed to the outside of the discharge mechanism, acting as a stable connecting hub to accurately transmit the buffering function; the connecting plate, as a carrier connecting the upper and lower parts, rationally distributes the force points of the second spring; the second spring absorbs vibration energy through elastic deformation, converting the impact force into elastic potential energy; combined with the bottom support base, which is in close contact with the ground through anti-slip rubber pads, the double buffer ensures the smooth operation of the discharge mechanism and reduces the impact of shaking on the screening accuracy.

[0019] As a further description of the above technical solution:

[0020] The discharge mechanism includes a screen box, a discharge port fixedly connected to the outside of the screen box, a slag discharge port fixedly connected to the outside of the screen box, a baffle fixedly connected to the inner wall of the screen box, and a screen mesh slidably connected to the inner wall of the screen box.

[0021] Through the above scheme: the discharge mechanism forms a complete closed loop for the processing of Chinese herbal medicine pieces. The feeding port realizes the input of materials, and the discharge port and slag discharge port respectively complete the collection of qualified medicinal pieces and the discharge of impurities. The division of labor is clear. The baffle on the inner wall of the sieve box changes the movement trajectory of the medicinal pieces, so that they pass through the sieve multiple times, improving the screening effect. The sliding sieve is easy to disassemble and clean, maintaining the screening accuracy. All components work together to ensure that the screening and collection process of Chinese herbal medicine pieces is efficient and orderly.

[0022] As a further description of the above technical solution:

[0023] The adjustment assembly includes a limiting post, one end of which is fixedly connected to the outside of the sliding post, and a spring is slidably mounted on the outer wall of the limiting post.

[0024] The above solution achieves dynamic stability and convenient maintenance of the screen by adjusting the components. A spring is fitted onto the limiting column, and during screening vibration, the position of the sliding column is adaptively adjusted through elastic deformation to buffer the force on the screen. When the screen needs to be cleaned, the spring assists the sliding column to smoothly disengage from the limiting column, allowing for quick disassembly of the screen, thus balancing screening stability and maintenance convenience.

[0025] As a further description of the above technical solution:

[0026] A switch is fixedly connected to the top of the sliding column, and the outside of the switch is slidably connected to the inner wall of the limiting hole.

[0027] The above solution provides a convenient structure for fixing and removing the screen: the sliding column, switch, and limiting hole form a convenient structure for fixing and removing the screen. When the switch is inserted into the limiting hole, the screen can be securely locked to ensure the stability of the screening process. When the screen needs to be cleaned and maintained, simply pull the switch to move the sliding column away from the limiting hole, and the screen can be quickly pulled out, greatly improving maintenance efficiency.

[0028] As a further description of the above technical solution:

[0029] The stainless steel frame has a stainless steel storage tank fixedly connected to its inner wall, and the outer side of the slide plate is slidably connected to the bottom inner wall of the stainless steel storage tank.

[0030] The above solution involves a stainless steel storage tank and a sliding plate to construct a precise feeding system. The stainless steel storage tank is firmly embedded in the inner wall of the frame to ensure the safe and hygienic storage of Chinese herbal medicine pieces. The sliding plate slides flexibly at the bottom of the storage tank. By controlling the size of the opening and the sliding frequency, the pieces are quantitatively and evenly dropped, providing a stable material supply for the subsequent screening process and ensuring the continuity and efficiency of the equipment operation.

[0031] This utility model has the following beneficial effects:

[0032] 1. In this utility model, when the screen is clogged by Chinese medicine residue, the sliding switch drives the sliding column to disengage from the limiting hole, which can quickly release the fixed connection between the screen and the screen box. This quick-release design does not require tools and can complete the screen disassembly in a short time, clear the blockage in time, and avoid affecting the screening efficiency and quality due to screen blockage.

[0033] 2. In this utility model, the starting motor and the follower plate drive the sliding plate to move, accurately controlling the amount of Chinese medicine falling in the stainless steel storage tank. In this way, the quantitative conveying of Chinese medicine slices can be realized, avoiding excessive feeding that would cause the screen to clog and affect the screening effect; it also prevents insufficient feeding that would reduce work efficiency, and the stable feeding amount can make the screening process more orderly and make the cooperation of each mechanism more coordinated.

[0042] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0043] Reference Figures 1 to 3This utility model provides an embodiment of an automatic screening and collection device for Chinese herbal medicine slices, including a discharge mechanism 1. The discharge mechanism 1 is the core part of the entire device, and its main function is to provide a stable spatial environment for screening and collecting Chinese herbal medicine slices. Through cooperation with other mechanisms, it realizes the orderly processing of Chinese herbal medicine slices. The screening mechanism 2 includes screens 21. The two screens 21 are slidably connected to the inner wall of the discharge mechanism 1. The screens 21 can effectively screen Chinese herbal medicine slices and separate Chinese herbal medicine slices of different sizes and specifications. Two limiting holes 24 are opened on the outside of the screens 21. The function of the limiting holes 24 is to cooperate with other components to limit the screens 21, ensuring that the screens 21 can maintain a stable position during operation and preventing them from shaking or shifting, which would affect the screening effect.

[0044] Specifically, the screen 21 in the screening mechanism 2 is a key component. After the Chinese herbal medicine pieces enter the discharge mechanism 1, they will fall onto the screen 21. Because the screen 21 has a specific aperture, Chinese herbal medicine pieces of different sizes and specifications will be separated under vibration or gravity. The limiting hole 24 on the outside of the screen 21 is closely matched with components such as the sliding column 23. When the device is running, the limiting hole 24 can accurately constrain the screen 21, making it firmly fixed in the working position, avoiding inaccurate screening due to shaking or displacement, thereby ensuring the screening effect and efficiency of the device.

[0045] Two sliding columns 23 are slidably connected to the inner wall of the screen 21. These columns 23 can slide along the inner wall of the screen 21, providing flexibility for its movement. An adjusting assembly 25 is slidably connected to one end of each sliding column 23. The adjusting assembly 25 includes a limiting column 252, one end of which is fixedly connected to the outside of the sliding column 23. A spring 251 slides along the outer wall of the limiting column 252. The presence of the spring 251 allows the adjusting assembly 25 to elastically adjust the position of the sliding column 23 to a certain extent. When the screen 21 is subjected to… When there is a certain pressure or the position needs to be adjusted, the spring 251 can play a role in buffering and adjustment. The top of the slide column 23 is fixedly connected to the switch 22. The outside of the switch 22 is slidably connected to the inner wall of the limit hole 24. After a period of use, the screen 21 will become clogged and affect the use of the device. At this time, the sliding switch 22 drives the slide column 23 to move and release the control between the screen 21 and the screen box 15, so that the screen 21 can be pulled out from the track inside the screen box 15 for cleaning and replacement, thereby ensuring that the screening effect of the screen 21 is always in good condition.

[0046] Specifically, the two sliding columns 23 on the inner wall of the screen 21 cooperate with the track on the inner wall of the screen box 15. During the screening process, the sliding columns 23 can slide slightly along the inner wall of the screen 21 to ensure that the screen 21 remains stable during vibration and to avoid stress concentration caused by rigid connection. In the adjustment component 25 connected to the sliding column 23, the spring 251 is sleeved on the limiting column 252. When the screen 21 is under pressure due to the accumulation of Chinese herbal medicine pieces or when the vibration amplitude changes, the spring 251 is compressed or rebounded to automatically adjust the position of the sliding column 23 and reduce the wear of the screen 21. When the screen 21 is blocked, the sliding switch 22 drives the sliding column 23 to disengage from the limiting hole 24, instantly releasing the screen 21 from the screen box 15, so that the screen 21 can be quickly pulled out for cleaning, ensuring screening efficiency and accuracy.

[0047] Reference Figure 1 , Figure 4 and Figure 5 The feeding mechanism 3 includes a stainless steel frame 36. The inner side of the stainless steel frame 36 is fixedly connected to the outside of the discharging mechanism 1, which plays a supporting and fixing role for the feeding mechanism 3 and ensures the connection stability between the feeding mechanism 3 and the discharging mechanism 1. The outside of the stainless steel frame 36 is fixedly connected to a motor 31. The motor 31 serves as the power source for the feeding mechanism 3 and can provide power to drive other components to move. The drive end of the motor 31 is fixedly connected to a follower plate 32. The follower plate 32 can move with the rotation of the motor 31 and transmit the power of the motor 31. The other end of the follower plate 32 is rotatably connected to a driven plate 33. The driven plate 33 rotates under the drive of the follower plate 32 and further transmits power. The other end of the driven plate 33 is rotatably connected to a slide plate 34. The slide plate 34 moves under the drive of the driven plate 33.

[0048] Specifically, in the feeding mechanism 3, the stainless steel frame 36 is precisely connected to the motor 31. After the motor 31 is started, it drives the follower plate 32 to rotate in a circle. The follower plate 32 converts the rotational power of the motor into an oscillating motion. The driven plate 33 and the follower plate 32 form a rotating pair, which further amplifies the power and changes the direction of motion. The oscillation is converted into a linear motion that pushes the slide plate 34. Under the drive of the driven plate 33, the slide plate 34 slides back and forth at the bottom of the stainless steel storage tank 35. By precisely controlling the size of the opening gap, the quantitative and uniform feeding of Chinese herbal medicine pieces is achieved, ensuring the stable operation of the screening mechanism 2.

[0049] A stainless steel storage tank 35 is fixedly connected to the inner wall of the stainless steel frame 36. A food-grade silicone sealing ring is connected between the stainless steel storage tank 35 and the stainless steel frame 36, which can effectively prevent the Chinese herbal medicine pieces from being contaminated by the outside world during storage, and also ensure the sealing of the storage tank. The opening of the feeding mechanism 3 drives the driven plate 33 to move the slide plate 34 to quantitatively drop the Chinese herbal medicine in the stainless steel storage tank 35, realizing the quantitative conveying of Chinese herbal medicine pieces and ensuring the orderly progress of the screening work. The external sliding connection of the slide plate 34 is connected to the bottom inner wall of the stainless steel storage tank 35. The sliding of the slide plate 34 can accurately control the amount of Chinese herbal medicine pieces falling, improving the accuracy and stability of feeding.

[0050] Specifically, the stainless steel frame 36 has a stainless steel storage tank 35 tightly fixed to its inner wall. The food-grade silicone sealing ring between the two plays a crucial role. Like a loyal guardian, it fits perfectly between the two, preventing external dust, bacteria and other contaminants from entering the storage tank. This keeps the Chinese herbal medicine slices in a clean storage environment. At the same time, the excellent sealing performance prevents odor leakage and moisture absorption of the slices, maximizing the preservation of the medicinal efficacy of the Chinese herbal medicine. When the feeding mechanism 3 is turned on, the motor drives the driven plate 33 to rotate regularly, which in turn pushes the slide plate 34 to slide smoothly on the inner wall of the bottom of the stainless steel storage tank 35. The distance and speed of each slide of the slide plate 34 are precisely designed to control the opening and closing size and time of the feeding port 11, so that the Chinese herbal medicine slices fall in a stable and precise amount, providing uniform and suitable material for subsequent screening work, which greatly improves the working efficiency and screening quality of the entire device.

[0051] Reference Figure 1 , Figure 4 and Figure 6 The discharge mechanism 1 includes a sieve box 15, with a feed port 11 fixedly connected to the outside of the sieve box 15. The feed port 11 is used for inputting Chinese herbal medicine pieces, making it convenient to send the Chinese herbal medicine pieces to be processed into the sieve box 15. A discharge port 12 is fixedly connected to the outside of the sieve box 15. The Chinese herbal medicine pieces that have passed the screening will be output from the discharge port 12 for collection. A slag discharge port 13 is fixedly connected to the outside of the sieve box 15. Some impurities or Chinese herbal medicine pieces that do not meet the requirements will be discharged from the slag discharge port 13. A baffle 14 is fixedly connected to the inner wall of the sieve box 15. The baffle 14 can play a certain role in blocking and guiding the movement of Chinese herbal medicine pieces in the sieve box 15, so that the Chinese herbal medicine pieces can be screened more fully in the sieve box 15. A screen 21 is slidably connected to the inner wall of the sieve box 15. The screen 21 is a key component for screening Chinese herbal medicine pieces. Different specifications of screen 21 can screen out Chinese herbal medicine pieces of different sizes.

[0052] Specifically, the sieve box 15, as the core carrier of the discharge mechanism 1, is designed with full consideration of the processing flow of Chinese herbal medicine pieces. The discharge port 11 is inclined and has a large diameter, which facilitates docking with the feeding equipment and ensures that the Chinese herbal medicine pieces can slide smoothly and quickly into the sieve box 15, avoiding accumulation and blockage. The discharge port 12 is located at a low position on the side of the sieve box 15 and is adapted to the height of the collection container. Under the action of gravity and vibration, the qualified Chinese herbal medicine pieces slide down the screen 21 to the discharge port 12, achieving efficient collection. The slag discharge port 13 is located at the bottom corner of the sieve box 15. Due to differences in weight and shape, impurities and unqualified pieces will preferentially fall from the gaps in the screen 21 during vibration and be discharged through the slag discharge port 13. The baffles 14 on the inner wall are staggered and inclined, like a "guide wall", which forces the Chinese herbal medicine pieces to change their trajectory in the sieve box 15 and pass through the screen 21 multiple times, ensuring that each piece of Chinese herbal medicine can be fully screened and improving the overall processing effect.

[0053] The drive mechanism 4 includes a support plate 41, the top of which is fixedly connected to the bottom of the discharge mechanism 1. The support plate 41 supports the discharge mechanism 1 and ensures its stability during operation. A second motor 42 is fixedly connected to the top of the support plate 41. The second motor 42 is the power core of the drive mechanism 4, providing power to rotate the eccentric wheel 43. The drive end of the second motor 42 is fixedly connected to the eccentric wheel 43. The eccentric wheel 43 rotates under the drive of the second motor 42, generating a vibration effect through its eccentric structure. The external fixed connection of the eccentric wheel 43 is... A slide rail 44 is provided, which provides a track for the sliding of the connecting base 45, so that the connecting base 45 can slide stably on the slide rail 44. The connecting base 45 is slidably connected to the outside of the slide rail 44. The sliding of the connecting base 45 on the slide rail 44 can transmit the vibration of the eccentric wheel 43. A counterweight 46 is rotatably connected to the outside of the connecting base 45. The presence of the counterweight 46 increases the stability of the device, and can also adjust the frequency and amplitude of vibration to a certain extent, so that the Chinese herbal medicine pieces in the discharge mechanism 1 can be better screened and the screening efficiency can be improved.

[0054] Specifically, the support plate 41, as the connecting hub between the drive mechanism 4 and the discharge mechanism 1, is made of thickened stainless steel. It fits tightly against the bottom of the discharge mechanism 1 with a large-sized flat surface and is fixed by multiple bolts, acting as a solid foundation to effectively disperse the vibration and pressure during device operation. After the motor 42 is started, the eccentric wheel 43 generates centrifugal force due to the shift in the center of gravity. During high-speed rotation, it continuously impacts the inner wall of the slide 44, forming a regular vibration. The slide 44 is an arc-shaped ring around the eccentric wheel 43, and its inner wall is polished with high precision. Combined with the roller design of the connecting base 45, it ensures smooth and uninterrupted vibration transmission. The counterweight 46 can change the installation angle and position by adjusting the bolts. According to the characteristics of Chinese herbal medicine slices, the vibration intensity can be flexibly adjusted. For example, when processing lighter slices, the center of gravity of the counterweight 46 is lowered to reduce the amplitude and avoid excessive bouncing of the slices, which would affect the screening accuracy. When processing harder slices, the center of gravity of the counterweight 46 is raised to enhance the vibration effect and accelerate the screening process.

[0055] The buffer mechanism 5 includes connecting blocks 52. Multiple connecting blocks 52 are externally fixedly connected to the outside of the discharge mechanism 1. The connecting blocks 52 are used to connect the buffer mechanism 5 to the discharge mechanism 1, ensuring that the buffer mechanism 5 can effectively buffer the discharge mechanism 1. A connecting plate 51 is fixedly connected to the bottom of the connecting blocks 52. The connecting plate 51 serves to connect and support the second spring 53. Two second springs 53 are fixedly connected to the bottom of the connecting plate 51. The second springs 53 are elastic and can absorb and buffer vibration and impact during the operation of the device, reduce the shaking of the discharge mechanism 1 caused by vibration, and ensure the stability of the device. A support base 54 is fixedly connected to the bottom of the two second springs 53. The support base 54 provides stable support for the entire device and also works with the second springs 53 to better achieve the buffering effect.

[0056] Specifically, the connecting block 52 is made of high-strength alloy material and is tightly welded to the outside of the discharge mechanism 1 in a ring array to ensure that the buffer mechanism 5 is stably connected to the discharge mechanism 1. The connecting plate 51 has a cross-shaped structure to increase the contact area with the second spring 53. Its surface is designed with threaded holes, and the second spring 53 is firmly fixed by bolts to prevent the spring from falling off under high-frequency vibration. The second spring 53 is made of manganese steel with a high elastic coefficient and has excellent fatigue resistance. When the vibration generated by the drive mechanism 4 is transmitted to the discharge mechanism 1, the second spring 53 will compress or rebound according to the magnitude of the impact force, and convert the vibration energy into elastic potential energy like a shock absorber, reducing the sway amplitude of the discharge mechanism 1. The bottom of the support base 54 is equipped with an anti-slip rubber pad to increase the friction with the ground. At the same time, the inside is filled with damping material, which works in synergy with the second spring 53 to further weaken the vibration and ensure the stable operation of the device.

[0057] Working principle: First, the Chinese herbal medicine slices are placed in the stainless steel storage tank 35. The food-grade silicone sealing ring between the tank and the stainless steel frame 36 ensures a sealed and clean storage environment. Then, the feeding mechanism 3 is activated. The motor 31 drives the follower plate 32 to rotate, which in turn drives the driven plate 33, causing the slide plate 34 to slide at the bottom of the stainless steel storage tank 35, so that the Chinese herbal medicine slices are quantitatively dropped into the sieve box 15.

[0058] After the drive mechanism 4 is started, the motor 42 drives the eccentric wheel 43 to rotate. The eccentric wheel 43 is connected to the base 45 through the slide rail 44 and works with the counterweight 46 to make the sieve box 15 vibrate. Under the action of vibration, the Chinese herbal medicine pieces move in the sieve box 15. Different sizes of pieces are separated by the screen 21. Qualified pieces are output from the discharge port 12, and impurities are discharged from the slag discharge port 13.

[0059] As the device is used, the screen 21 may become clogged. In this case, the sliding switch 22 moves the sliding column 23, releasing the screen 21 from its fixation and allowing it to slide out of the track inside the screen box 15 for cleaning and replacement. The spring 53 in the buffer mechanism 5, through the connecting block 52 and the connecting plate 51, buffers the impact force generated by the vibration of the screen box 15, ensuring stable operation of the device. The various mechanisms work together to achieve automatic screening and collection of Chinese herbal medicine pieces.

[0060] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
